+.SH NAME
+.TP
+scapin - Scan path insertion
+.so man1/alc_origin.1
+.SH SYNOPSIS

+\f4scapin [\-VRB] [\-P file] Input_name Path_name Output_name
+.br
+.SH DESCRIPTION
+\fBSCAPIN\fP is an automatic scan architecture generator for gate level netlists.
+\fBSCAPIN\fP insert a scan path in the netlist \fBInput_name\fP and drives 
+a new netlist \fBOutput_name\fP.
+This scan path contains all registers specify in the file \fBPath_name\fP.path
+(see below for the exact syntax).
+\fBSCAPIN\fP add 3 new connectors to the netlist: scan_in, scan_out and
+scan_test in order to control the scan path.
+Eventually \fBSCAPIN\fP can add an output buffer before the output connector
+scan_out (option -B).
+.br
+
+.SH OPTIONS
+.TP 10
+\f4\-V\fP
+Verbose mode on.
+Each step is displayed on the standard output.
+.TP 10
+\f4\-R\fP
+All registers of the scan path are replaced by scannable register cell (called reg-mux).
+(With the default option a simple multiplexor is added just before all registers
+of the scan path).
+.TP 10
+\f4\-B\fP
+Adds an output buffer before the output connector scan_out.
+.TP 10
+\f4\-P file\fP
+Specifies a parameter file (with extention .scapin) containing the properties of
+all cells needed for the scan path insertion.
+(see below for the exact syntax)
